Sand or recycled glass as the filter medium? This practical comparison shows where glass filter media excels in filtration fineness, backwash water and service life, and when silica sand remains the right choice.
Automatic or manual backwash valve for your pool? This guide compares both designs and shows what really matters when it comes to selection, sizing and retrofitting.
The multiport (6-way) valve controls which path the water takes through the sand filter. Once you know each position and its pitfalls, you operate the system safely and protect the spider gasket, the key wear part. Design and mounting location of the multiport (6-way) valve The multiport (6-way) valve – also called a multiport or…
It is not the pump but the media inside the filter tank that determines how finely your pool water is cleaned. Quartz sand, processed filter glass and filter balls differ in particle retention, weight, service life and water consumption – and therefore, above all, in the cost over several years. The Three Filter Media at…
If your pool pump delivers no water after being switched on, or draws air bubbles during operation, there is almost always a suction-side cause behind it. With a fixed checking sequence from common to rare, you’ll quickly locate the spot – without needlessly replacing parts. Priming vs. Drawing Air – First Narrow Down the Fault…
A pool pump is correctly sized when it circulates the entire pool volume within the desired time while reliably overcoming the system’s head. Pumps chosen too large waste electricity, while those chosen too small fail to achieve the necessary circulation. This article walks you through the calculation, from the pool volume via the head and…
